RickyD:
I can see you have a lot of posts on this forum and are probably much more experienced with hard kicking guns than I am.
I'll try to clarify & simplify my earlier remarks.
I think we're both saying the same thing. Just coming at it from different directions.
Momentum is the product of mass and velocity.
Impulse is the produce of force and time.
MOMENTUM equals IMPULSE. MxV = FxT. If you fire a 125 gr. Cor Bon +P round, the velocity of the gun recoiling in your hand is going to depend on the weight of that gun.
So it's no mystery that your 12 oz. 360PD kicks much more than my 42 oz. (loaded) 686. Newton's laws of motion give us an objective way to compare stuff.
Unless I use a Pachmayr grip, the 686 kills my arthritic thumb. I can't imagine shooting that same load in a gun that kicks 3 1/2 times harder..... Actually - I can. I fired one round and quit.
